Suunto MC-2 G 6400/360 Military Compass
Suunto MC-2 G 6400/360 Military Compass is a professional field navigation tool built for demanding military, rescue and expedition use. It combines a transparent rectangular baseplate with a rotating protractor capsule, adjustable declination correction, and a hinged mirror lid for accurate sighting. The compass is non-radioactive, magnetic, unmounted and designed to remain reliable in extreme weather conditions.
This version includes a MILS (0–6400) primary scale for MGRS-style work and a 0–360° secondary scale, plus a global balancing needle that functions across all magnetic zones worldwide. A built-in clinometer and extensive luminescent markings support advanced field use, including slope measurement and night navigation.

Declination Correction
The angle between the orienting arrow and orienting lines can be adjusted to compensate for declination. Adjustment is done by turning the sprocket with the flat screwdriver tool on the lanyard. The correction scale is in degrees (2° resolution), numbered every 20°, extending 90° E (+) and 90° W (-).
Clinometer

FAQ
What is the difference between 6400 mil and 360°?
Both scales represent a full circle. Degrees use 360 units, while the military mil scale uses 6400 units, allowing finer angular measurements for tactical navigation and target/bearing work.
Is this compass suitable for worldwide use?
Yes. The global balancing needle works across all magnetic zones and is designed to function at all Earth magnetic field locations.
How do I adjust declination on the MC-2 G?
Declination is adjusted using the flat screwdriver tool attached to the lanyard. The correction scale is in degrees with 2° resolution and supports ±90° east/west adjustment.
What is the clinometer used for?
The clinometer measures slope/inclination (0 to ±90°). It is useful for terrain evaluation, route planning, and estimating gradients in the field.
Is the compass waterproof?
Yes. It is waterproof to all practical depths. Any cavities may fill with water and then drain after exposure.
